In this model there are male and female fish which carry genes for color expression. Homozygous recessive results in orange coloring while heterozygous or homozygous dominant results in green coloring. Male fish and female fish will breed with one another and produce offspring and pass on their genes.\n\nPressing \"Shark Attack\" introduces the invasive Shark species to the model. Sharks prey on fish they are able to see against the background coloring.
